This paper reports a very unusual case of a melanocytoma (nevus) of the ciliary body with involvement of the overlying sclera which masqueraded as a malignant melanoma.
Report of Patient
A 62-year-old white man noted that a dark growth was present on his left sclera at the 4:30 o'clock meridian for about five months. The patient did not observe any change in size of the lesion, nor did it give him any symptoms. There was no history of injury to the area.About one month prior to admission, two ophthalmologists examined the patient. Both made a diagnosis of malignant melanoma of the ciliary body and advised enucleation. The patient was referred for still another opinion.His visual acuity was 6/7.5 in the right eye and 6/6 in the left with correction. The tension was 15 mm Hg Schiøtz in each eye. Two darkly pigmented lesions were seen on the sclera
